Installation and Maintenance Guide

Installation Precautions

Pipeline Cleaning: Thoroughly clean the inlet and outlet pipes before installation to prevent welding slag and impurities from entering 

the pump body and damaging the stator/rotor.

Inlet/Outlet Connection: Ensure reliable inlet and outlet pipe connections to avoid pipe stress on the pump body.

Pipe Diameter Matching: The inlet pipe diameter should not be smaller than the pump inlet diameter to prevent cavitation.

Dry-Run Protection: It is recommended to install a dry-run protection device, as dry running of the stator will cause rapid damage.

Maintenance Recommendations (ALLDUR® Stator Advantages)

ALLDUR® stators have an extremely long service life and can safely and economically pump media over a wide temperature range

 (-30 °C to +100 °C), requiring no maintenance or replacement for many years.

OPTIFIX™ series supports quick maintenance, allowing stator and rotor replacement without disassembling the inlet and outlet pipes.

It is recommended to regularly check the sealing condition and replace worn seals promptly.

Standby pumps should be periodically rotated to prevent stator sticking.
